Transmission

[Command1][Command2][ ][Set ID][ ][Data][Cr]

*[Command 1] : First command to control the TV. (j, k, m or x)

*[Command 2] : Second command to control the TV.

[Set ID] : You can adjust the set ID to choose*

		desired monitor ID number in option
		menu. Adjustment range is 1 to 99.
		When selecting Set ID ‘0’, every con-
		nected set is controlled.
		Set ID is indicated as decimal (1 to 99) on
		menu and as Hexa decimal (0x0 to0x63)
		on transmission/receiving protocol.
* [DATA]		: To transmit command data.
		Transmit ‘FF’ data to read status of com-
		mand.
*	[Cr]	: Carriage Return
		ASCII code ‘0x0D’
*	[ ]	: ASCII code ‘space (0x20)’

OK Acknowledgement

[Command2][ ][Set ID][ ][OK][Data][x]

*The set transmits ACK (acknowledgement) based on this format when receiving normal data. At this time, if the data is data read mode, it indicates pres- ent status data. If the data is data write mode, it returns the data of the PC computer.

Error Acknowledgement

*When setting the 17 to 24, a menu does not appear on screen.

*Note : During USB operations such as Dvix or EMF, all commands except Power(ka) and Key(mc) are not exe- cuted and treated as NG.

[Command2][ ][Set ID][ ][NG][Data][x]

*The set transmits ACK (acknowledgement) based on this format when receiving abnormal data from non-viable functions or communication errors.

Data 00: Illegal Code
